On my Dell mini 1010n I opened a new partition and loaded 12.04, then changed the repository to qualtal and upgraded the system to 12.10. Then noticed the screen brightness was set to about half with the keys for up and down not working. And it wouldn't go to sleep. Changed to
and removedCode:GRUB_CMDLINE_LINUX_DEFAULT="quiet console=tty1 acpi_osi=Linux mem=896mb"in /etc/pmCode:ADD_PARAMETERS='--quirk-vbemode-restore'
Results: nothing worked. Brightness low and no suspend much less resume.
But everything else was fine, so far. gtkperf ran at 36.50, about the same as in 12.04.
It's a start, huh, Luca?
